Steels for quenching and tempering (QT steels)

For improved cutting properties we sell a few steels with a controlled

sulphur content of 0.020 - 0.035 %, and also with added lead.

Unalloyed QT steels

Unalloyed QT steels are preferred for low-stress components in

the construction of machinery and motor vehicles.

Machine components are manufactured from QT steels, i f they are

subject to such high tensile, compressive, bending and/or torsional

stresses - whether sta tic, a lternating or sudden - that the un iversal

structural steels, with their mechanical properties, are no longer

adequate.

Case-hardening steels

Case-hardening steels are machinery steels with a relatively low

carbon content and a surface layer which is carburised or car-

bonit rided prior to hardening. After hardening of the surface layer,

these steels have a high capacity for retaining their hardness and

are very resistant to wear, whils t the core mater ial is characterised

mainly by a good degree of ducti lity.

Tool steelsTool steels are high-quality steels suitable for working or processing

of materials and for handling and measuring workpieces. They

exhibit a high value of hardness, high resistance to wear and high

toughness appropriate to the use for which they are intended.

Tool steels for cold working are case-hardened if the surface temperature

is no more than 200 C.

Heat-resistant steels

Heat-resistant steels are mater ials which retain their mechanical

properties at temperatures up to 580 C.

The same applies to elevated temperature steels, though resistance

here extends to about 800 C.

Stainless steels

Stainless steels are those which are distinguished by the fact that

they are specially resistant to chemically aggressive substances;

they generally have a chromium content of not less than 12 % by

weight and a carbon content not exceeding 1.2 % by weight.

Induction hardening:

Induction hardening is used in a ll cases where there is a need for

hard and wear-resis tan t sur faces. The advantage of induct ion

hardening is that only the surfaces subjected to wear are parti ally

hardened. The non-hardened areas can still be machined at low

cost.

In consultation with our customers we carry out such surface layer

hardening processes on rods with o rdered lengths up to 7 metres .

Examples of use include: linear guides, torsion bars, spl ined shafts,

chain guides, knives and similar items.

To meet different requirements in terms of hardness and wear-

resis ting propert ies we sell una lloyed and alloyed QT steels as well

as ball and rolle r bearing steels and tool steels.
